D22.12
Melanocytic nevi of left eyelid, including canthus
Clinical Classification Guidelines
Medical Intelligence & Overview
Melanocytic nevi, commonly known as moles, are benign skin growths made up of pigment-producing cells called melanocytes. When these nevi appear on the eyelid, particularly on the left side or near the inner corner known as the canthus, they are categorized under ICD-10 code D22.12. While generally harmless, monitoring and understanding these nevi are important for maintaining eye and skin health.
Causes & Symptoms
Clinical Causes: Genetic factors that influence skin pigmentation and mole development Sun exposure, which can stimulate melanocyte activity and growth Family history of benign or atypical nevi Skin type and pigmentation, with lighter skin tones being more prone to developing nevi Hormonal changes that can influence melanocyte activity, especially during adolescence or pregnancy
Key Symptoms: Small, uniformly pigmented spot or mole on the eyelid Color variation within the nevus, typically brown, black, or a mixture Shape that is symmetrical and well-defined Stable size over time, although some may grow slightly Absence of symptoms such as pain, itching, or bleeding
Diagnostic & Treatment
Diagnosis Path: Diagnosis of a melanocytic nevus of the left eyelid involves a thorough physical examination by a healthcare professional. Dermatologists or ophthalmologists may assess the size, shape, color, and borders of the nevus. In some cases, dermoscopy—a specialized skin imaging technique—is used to evaluate the lesion more clearly. If there are irregular features or changes over time, a biopsy might be performed to rule out other conditions, including melanoma. Regular skin checks are important for monitoring.
Treatment Protocols: Surgical excision: removal of the nevus through minor surgery, often under local anesthesia Shave excision: slicing off the lesion at skin level for superficial nevi Laser removal: using targeted laser therapy in suitable cases Cryotherapy: freezing the lesion with liquid nitrogen, less common for eyelid nevi due to delicate skin
